I just wrote my first Python program. It occurs to me, given the generally grey colour of my beard, that this may be the last time I learn a new programming language. Which, frankly, would be OK, it’s real work. This thing scans all the feeds coming out of Planet Sun using Mark Pilgrim’s Universal Feed Parser, detects any that have changed in the last day, and pings weblogs.com, technorati.com, and blo.gs to let them know. (Question: who else should be pinged? Answer: thanks to the many people who wrote about Ping-o-matic; doesn’t quite fit our bill, but interesting.) It’s only 57 lines of code, but I had to learn a modest amount of Web wrangling, string munging, time arithmetic, and data structure walking to get it going. I suspect it’s not a very good Python program, but I can live with that. If you’re going to scale the Pythonic slopes, you’ll need one browser tab open to Dive Into Python, another to the Python Tutorial, a shell window handy where you can type things like pydoc time, and a nontrivial chunk of Python code in a nearby editor buffer (I used the Feed Parser) so you can look up idioms. At the end of the day, the code looks distinctly weird to my eye, kind of ragged without a supporting visual lattice of {’s }’s, and ;’s. But I’m sure you get used to it quickly.
